Extra funding for Lyttelton Harbour wastewater

Extra funding has been approved to complete the upgrade of the wastewater services for the communities around Whakaraupō Lyttelton Harbour.

We originally budgeted $54 million for the Lyttelton Harbour Wastewater Project that will bring an end to the routine discharge of treated wastewater into the harbour. However, the budget has now been increased to $60.5 million.

The extra money is needed to redesign and construct some elements of the pump stations, work around some difficult and unforeseen ground conditions and slips, and cover the costs of COVID-19 related delays.

We expect to complete construction work early next year. Thank you for your ongoing patience as we complete this project.

What are we working on?

We're converting the treatment plants at Governors Bay, Diamond Harbour and Lyttelton to storage tanks. These tanks are designed to temporarily store wastewater during times of high rainfall.

We're also connecting the Heathcote Valley pipeline into the pipe through the Lyttelton Tunnel.

Commissioning

One of the biggest parts of this project is the commissioning of the whole system. We need to be able to control the stations remotely from the Bromley Treatment Plant and we test all of this by running clean water through the pipes first.
